BlueSpace has built a next gen command and control app using their security middleware and Google Earth Enterprise, that show just how far you can take GEE as a visualization environment. They're demostrating MLS C2 at 5 different locations for Coalition Warrior Interoperability Demonstration (CWID), a joint exercise between US, UK, Canada, Australia and NATO (among others) to help find and prove technologies and systems that can help better orchestrate coalition warfare. For the exercise, BlueSpace worked with its partners to model around 100 units including aircraft, ground units and boats and of these units move around in real-time based on data feeds being fed to app.
In 2nd World War, the allies used maps with little models to show units, and moved them with poles to update their locations. With modern radar and GPS systems, things are bit more sophisticated, but much of the mapping functionality has lagged behind. Many of the currently deployed C2 systems use flat, two-color vector maps with triangles showing units.
